From Form to Usercontrol

Form Code
public string ID
{
    get { return textBox1.Text; }
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
    userControl11.ID = ID;
}

Usercontrol Code
public string ID
{
    set { textBox1.Text = value; }
}

Although some stuff are inherited when creating a custom user control, for the most part you have to define your own properties. (like text value, etc..)

I would take a look at this: http://msdn.microsoft.com/en-us/library/6hws6h2t.aspx good luck!

You could add to your User Control code a public property that delegates into the TextBox's Text property:

public string MyTxtBoxValue { get { return this.txtBox.Text; } }

And you could also have a setter to that, of course, if needed.

What you don't want to do, however, is exposing the whole TextBox by making it public. That is flawed.

There are multiple ways to access your user control text box data. One way to accomplish this would be to expose the text box on the user control at a scope that can be accessed via the form it's loaded on. Another way would be raising an event on the button click of the user control and subscribing to it on the parent form.
